Lipid composition and oxidative changes in diabetes and alcoholic diabetes rats

Background: The investigating of study was expected to the lipid composition of diabetes and alcoholic diabetes in plasma and erythrocyte membrane biochemical profile in rats. Diabetic male Wistar Streptozotocin (STZ)-induced rats were used experimental models. Control rats (C) were maintained group I, received glucose (i.e., caloric equivalent), diabetic induced rats (STZ) group II, and group III alcoholic treated and IV diabetic and alcoholic treated rats which received 20 % (v/v) alcohol in water, administered through stomach tube (5 g/kg body weight/day). Results: STZ-induced diabetic hepatic damage in rats was observed which leads to the increased plasma lipid peroxidation, nitrate and nitrite levels. Diabetic and administration alcohol rats also suggestively lesser the activities of antioxidants, glutathione peroxidase, glutathione S-transferase, superoxide dismutase, catalase and reduced glutathione when related with control rats (group I). Plasma enzymes are normal levels and renovate the enzymic and non-enzymatic antioxidants level in experimental groups. Conclusion: The present data point out that the nitric oxide scavenging levels increased and may possibly protect and adjacent to oxidative stress and free radicals in diabetic hepatopathy rats and histopathological studies were identified in regular hepatic cortex of Group II, III and IV of animals with diabetes, alcoholic and alcohol-induced diabetes rats.
